reoccuring train crash

so, im at the platform alone, its an underground station. i get on the train and there are a lot of faceless people on it.
we head through a wide underground area and the all of a sudden the front end of the train comes off the track, like its floating.
It curves around and smashes into the front of the car I am on., im around 4 cars back in the second to last car.
then as the flames begin to engulf the car I wake up.
